[Adjuvant chemo-endocrine chemotherapy with gastrin antagonist after resection of liver metastasis in colorectal cancer].

This study was designed to determine whether or not chemo-endocrine therapy after the resection of liver metastasis from colorectal cancer would prevent re-recurrence in the liver. Postoperatively, seven patients received proglumide gastrin antagonist (1,200 mg/day) +5'-DFUR (800 mg/day) orally for 2 years. MMC 6-10 mg and ADR 20 mg were infused every two weeks alternately for 1 year via catheter in the common hepatic artery. After median follow-up of 39 months, re-recurrence rate in the remnant liver after hepatic resection was 14% (1/7) for patients with chemo-endocrine therapy and 52% (24/46) for the controls. These results suggest the possibility that chemo-endocrine therapy is effective to prevent re-recurrence of liver metastasis in patients with colorectal cancer.
